Analytical calculation of two-center coulomb and hybrid integrals with the correlation factor r 12 k

Israfil I. Guseinov: A pioneer of the quantum theory of atomic, molecular, and nuclear systems*

“…In Refs. , by the use of Guseinov's symmetrical and unsymmetrical one‐range addition theorems for integer and noninteger n STOs and complete sets of ‐METOs, one‐ and two‐electron multicenter electron‐repulsion integrals with the arbitrary location of STOs are expressed in terms of overlap integrals. The final results are of a simple structure and are, therefore, especially useful for machine computations.…”

“…, the prepared computer program for Guseinov's CHFR equations can be successfully applied to the study of various properties of atomic, molecular, and nuclear systems. Note that all of the one‐ and two‐electron multicenter integrals over STOs arising in the solution of CHFR equations have been evaluated using Guseinov's symmetrical and unsymmetrical one‐range addition theorems …”
